40V Dual Op Amp Delivers Precision and Low Noise at Half the Power of Competitive Devices

The ISL28218 is a dual op amp featuring single supply operation and ground referred inputs, and a rail-to-rail output that offers design flexibility when operating from a single or dual supply. The ISL28218's rugged input stage provides protection and wide common-mode voltage range that extends 0.5V below the negative rail. This allows designers to use the ISL28218 in harsh environments as well as in sensor applications where the signal can drop below ground.

The ISL28218 draws just 1.1mA maximum supply current, which is half of the current required by competitive devices. This provides designers added design flexibility in how they utilize their allocated power budget.

The ISL28218 is ideal for applications that require better DC accuracy and AC performance, including instrumentation, data acquisition, precision power supplies and industrial controls. The ISL28218 provides industry leading temperature drift, resulting in improved system accuracy over temperature. In addition, the ISL28218's low noise results in a higher signal to noise ratio. Ultimately, Intersil's newest 40V op amp provides the industry's best combination of accuracy, low noise and power consumption.

Fabricated using Intersil's proprietary precision silicon-on-insulator (SOI) bipolar process technology, the ISL28218 exhibits extremely robust latch-up immunity. It features high ESD ratings of HBM 3keV and machine model 300V, allowing it to perform reliably in harsh industrial environments over the entire -40C to +125C temperature range.
